How does drawing a rectangle support the idea of composing a larger unit from smaller units

Answer:

When you think rectangles, you think areas. Small areas aggregate to form bigger ones.

If you drew a rectangle, it's easy to divide it into smaller units by simply taking a line through its midsection from one length to the other and one width to the other. One can either form smaller squares or rectangles from a larger one.

When that is one, you'd have taken the larger area of a rectangle which is simply the product of the value of its length and it's the breadth, and divided it into smaller units.

Cheers!

who does the number, of zeros in the product of 8 and 5000 compara to the number of zeros in the factors ? explain.

mezya [45]

If one of the numbers we multiply (factors) has zeros at the end, and the other isn't a fraction: all those zeros will stay in the product.

But there might be additional zeros if the other numbers in the factors (the numbers which aren't 0) mupliply to "end" in zero and this is the case here:

8*5=40.

so the product will be 40 and the zeros of the 5000:

40 000

the number of zeros in the product will be bigger than the number of zeros in the factors if the non-zero parts of the fractions multiply to a number with 0 at the end.

Marco sews pillow and comforter sets. Each set has 2 pillows and 1 comforter. He uses 0.75 yards of material for each pillow and

Aliun [14]

Answer:

He would need 58 yards of material.

Step-by-step explanation:

If there are 4 sets of pillows and comfoters, that means there are 8 pillows and 4 comfoters.

If each pillow uses 0.75 yards of material, 8x0.75= 6

If each comfoters uses 13 yards of material, 4x13= 52

6+52= 58 yards of material.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

5x - 2y = 9

3x + 4y = -5

Step 2: Rewrite systems

10x - 4y = 18

3x + 4y = -5

Step 3: Solve for x

Add to equations together: 13x = 13
Divide 13 on both sides: x = 1

Step 4: Solve for y

Define: 3x + 4y = -5
Substitute in x: 3(1) + 4y = -5
Multiply: 3 + 4y = -5
Isolate y term: 4y = -8
Isolate y: y = -2

And we have our final answer!
